I actually have the fix courtesy of user MagicSmoke and he wrote
I just got said tv off c-list today. Said would power on and work fine some days, other times power on with no backlight after V logo but had sound.
If anyone has problems like these it is because they cheaped out on ground points for the PSU and main.
2 screws for PSU on Primary side and 2 metal spring tabs held in by plastic lock spacers and then just taped down on back of panel for the secondary side.

On the psu in this set the plastic lock spacer was not holding the metal spring tab to the psu board tightly. Causing a fault on backlight circuit shutting it down.
I found it by pressing on psu while backlight was on, the loose connection would cause the b/light to flicker.
I figured wth and soldered a wire from ground plane to the metal tab to make sure it has a good connection.
It now turns on everytime, tapping on psu has no effect on b/light and cost nothing to repair (I did add better tape to hold tabs down with).
So basically all i need to know is where exactly im soldering the wire to im not sure what a ground plane is or where its located according to the picture linked above. Please if anyone can help me as to where i need to solder this wire to fix it so i can get back to Overwatch it would be highly appreciated.
